TLS

As explained in Data-Driven Cybersecurity

TLS is a cryptographic protocol that provides secure communication over a network by protecting data confidentiality and integrity and authenticating endpoints.

Transport Layer Security (TLS) is a cryptographic protocol for protecting data in transit. It preserves the privacy and integrity of internet communications and supports endpoint authentication, making it central to secure exchanges between devices and servers. section 7.3.2

TLS supports practical security goals during network communication:

  • Protects exchanged data from eavesdropping, interception, and theft while it travels between systems. section 7.3.2
  • Helps ensure that received data is complete and unaltered by preventing tampering during transmission. section 7.3.1 section 7.3.2
  • Underpins HTTPS, securing communication between a user’s device and a server during online transactions. section 7.3.1
  • Requires current protocol versions: TLS 1.2 and later are treated as secure, while TLS 1.1 and earlier are susceptible to known attacks. section 7.3.1

Securing an online transaction

When a user sends sensitive information to a server through HTTPS, TLS encrypts the communication and helps prevent an interceptor from reading, copying, or altering the data in transit. section 7.3.1 section 7.3.2

How Data-Driven Cybersecurity covers it

How deep it goes
Explains TLS’s security role, threats, HTTPS use, endpoint authentication, and version requirements without detailing protocol internals.
Examples
Uses HTTPS between a user device and server and contrasts TLS with VPN protection for transmitted data.
What you can do after
Evaluate TLS choices by checking protocol versions and identifying protections against eavesdropping, tampering, and endpoint risks.
How it connects
Connects TLS with HTTPS, endpoint authentication, encryption, hashing algorithms, and virtual private networks.
